【摘要】：隨著智能電網(wǎng)、智能家居的普及,將會(huì)有大量電氣設(shè)備通過(guò)網(wǎng)絡(luò)實(shí)現(xiàn)數(shù)據(jù)交換、信息共享和遠(yuǎn)程接入,電力線通信PLC(Power Line Communication)技術(shù)將在其中發(fā)揮重要作用。PLC利用現(xiàn)有電力線,通過(guò)載波方法將模擬或數(shù)字信號(hào)進(jìn)行傳輸,不需要重新架設(shè)網(wǎng)絡(luò),只要有電線,就能進(jìn)行數(shù)據(jù)傳遞。電力系統(tǒng)網(wǎng)絡(luò)需要對(duì)PLC設(shè)備進(jìn)行有效的管理,這也將是本文的核心任務(wù)。本文的開(kāi)發(fā)環(huán)境由Miineport和IT900兩個(gè)開(kāi)發(fā)板及其配套軟件構(gòu)成。Miineport是一個(gè)串口聯(lián)網(wǎng)模塊,IT900是電力線通信模塊,兩者之間用串口連接,并以Miineport作為主機(jī),可以實(shí)現(xiàn)基于以太網(wǎng)接口的電力線通信設(shè)備。本文將設(shè)計(jì)實(shí)現(xiàn)該功能的系統(tǒng)軟件并給出具體的代碼,這些代碼編譯過(guò)后的可執(zhí)行文件通過(guò)以太網(wǎng)口 TFTP協(xié)議下載到Miineport中運(yùn)行,Miineport通過(guò)串口控制IT900,進(jìn)而控制電力線網(wǎng)絡(luò)。為了解決對(duì)電力線網(wǎng)絡(luò)設(shè)備的集中管理與維護(hù),本文設(shè)計(jì)了適用于小型混合網(wǎng)絡(luò)的管理系統(tǒng),并給出了管理系統(tǒng)中使用的操作與相關(guān)指令格式。此外,在設(shè)計(jì)該系統(tǒng)時(shí),還兼顧了電力行業(yè)現(xiàn)行傳輸規(guī)約,應(yīng)用開(kāi)發(fā)者可以在此基礎(chǔ)上實(shí)現(xiàn)具體的應(yīng)用功能。最后在實(shí)驗(yàn)室進(jìn)行了組網(wǎng)與測(cè)試,利用實(shí)驗(yàn)室現(xiàn)有的網(wǎng)絡(luò)設(shè)備,結(jié)合一系列測(cè)試軟件驗(yàn)證整個(gè)電力線通信系統(tǒng)的功能。根據(jù)系統(tǒng)組網(wǎng)實(shí)驗(yàn),本文設(shè)計(jì)的電力線通信系統(tǒng)軟件能夠運(yùn)用于中低壓配電網(wǎng)、接入網(wǎng)等實(shí)際網(wǎng)絡(luò)環(huán)境。系統(tǒng)實(shí)現(xiàn)了對(duì)電力線網(wǎng)絡(luò)中各個(gè)節(jié)點(diǎn)設(shè)備的管理與配置,主從設(shè)備之間可以進(jìn)行簡(jiǎn)單的自治,也可以通過(guò)局域網(wǎng)對(duì)整個(gè)電力線網(wǎng)絡(luò)進(jìn)行管理。此外,系統(tǒng)也可以依據(jù)現(xiàn)行電力行業(yè)傳輸規(guī)約傳輸報(bào)文。
[Abstract]:With the popularity of smart grid and smart home, there will be a large number of electrical equipment to realize data exchange, information sharing and remote access through the network. Power Line Communication (PLC) technology will play an important role in it. PLC will make use of existing power lines. The analog or digital signal is transmitted by the carrier method, so it is not necessary to re-set up the network, as long as there is a wire, the data can be transmitted. Power system network needs effective management of PLC equipment, which will be the core task of this paper. The development environment of this paper is composed of two development boards, Miineport and IT900, and its supporting software. Miineport is a serial port networking module. It is a power line communication module. The interface between them is connected by serial port, and the Miineport is used as the host. Power line communication equipment based on Ethernet interface can be realized. In this paper, the system software to realize this function is designed and the specific code is given. The executable files compiled by these codes are downloaded to the Miineport via the Ethernet port TFTP protocol to run the Miineport to control IT900 through serial port, and then to control the power line network. In order to solve the problem of centralized management and maintenance of power line network equipment, this paper designs a management system suitable for small hybrid network, and gives the operation and related instruction format used in the management system. In addition, in the design of the system, the current transmission protocol of power industry is also taken into account, and the application developer can realize the specific application function on this basis. Finally, the network and test are carried out in the laboratory. The functions of the whole power line communication system are verified by using the existing network equipment and a series of test software. According to the system networking experiment, the power line communication system software designed in this paper can be applied to the medium and low voltage distribution network, access network and other practical network environment. The system realizes the management and configuration of each node equipment in the power line network. The master and slave equipment can be easily autonomous or the whole power line network can be managed through the local area network. In addition, the system can also transmit messages according to the current power industry transmission protocol.
